I created a website for the game and added some sound effects.
Next steps:
current Alpha-Download
Android Libgdx version: Download
Desktop libgdx version: Download
And I created some gifs to show how the game works.
Another issue that happened to me when playing on a Nexus 9, was that the time progresses significantly slower than realtime when the baby “falls” and “slides” on the function graph. The seconds elapse at around one third of the realtime. Oddly this does not happen when swiping with the finger all over the viewport whilst the animation runs. As long as I touch and swipe around with the finger, the time progresses normally (faster) equal to realtime. When stopping the swiping, the time again progresses slower.
Mhh, I updated my nexus 9 and tried it … and you are right and I have no idea.
When the user presses a button, the input is saved and in the next update/render step it is evaluated. Why the nexus 9 makes such strange things … I dont know, I have to debug it at home.
Congratulations about this “game”
I’m really happy to see it. Great idea, simple but beautiful interface.
Now you can play the game in your browser, you don’t have to download it. 
I removed some bugs and if the render/update cycle needs too long, then the game renders less objects.
Next step is to publish it to the playstore. The native android version is much faster then the browser version.
Well—it appears as though I have a game to play through!
Are you going to remove the keypad should the game be played from a desktop computer? It seems to me it covers slightly too much of the screen. ???
Nice job, btw on my nexus 5x entering the formula is a little bit slow
